Abstract (en)
[origin: DE19546297A1] A method and airbag system are proposed for reducing the kinetic energy of a vehicle occupant during a road accident involving marked negative acceleration. The airbag system has a control unit for inflating an airbag. The control unit activates the airbag system on the basis of electrical signals from an on-board acceleration sensor. Other sensor elements are also provided for determining those parameters on which the individual kinetic energy of the vehicle occupant depend. Electrical signals representing those parameters are forwarded from the sensor elements to an electronic evaluation system linked to the control unit and said evaluation system on the basis of the signals calculates a point in time t4 at which the vehicle occupant is likely to come into contact with the inflated airbag; the electronic evaluation system then calculates a point in time t2 preceding the point t4 at which inflation of the airbag should begin and forwards this to the control unit which triggers inflation of the airbag at the point in time t2. This maximises protection of the vehicle occupant sitting in front of the airbag and prevents injury to the occupant.
